Abstract

Muscle-shortening velocity and hence power have been shown to increase in the presence of nitric oxide (NO). NO availability increases after consuming nitrate (NO 3-). Ingestion of NO 3-rich beetroot juice (BRJ) has increased muscle power in untrained adults. Purpose: This study determined whether NO 3- supplementation could acutely enhance maximal power in trained athletes. Methods: In this double-blind, crossover study, 13 trained athletes performed maximal inertial-load cycling trials (3–4 s) immediately before (PRE) and after (POST) consuming either NO 3-rich (NO3) or NO 3-depleted (PLA) BRJ to assess acute changes (ie, within the same day) in maximal power (P MAX) and optimal pedaling rate (RPM opt). Participants also performed maximal isokinetic cycling (30 s) to assess performance differences after supplementation. Results: 2 x 2 repeated-measures ANOVA indicated a greater increase in P MAX from PRE to POST NO3 (PRE 1160 ± 301 W to POST 1229 ± 317 W) than with PLA (PRE 1191 ± 298 W to POST 1213 ± 300 W) (P = .009; ηp2 = 0.45). A paired t-test verified a greater relative change in P MAX after NO3 (6.0% ± 2.6%) than with PLA (2.0% ± 3.8%) (P = .014; d = 1.21). RPM opt remained unchanged from PRE (123 ± 14 rpm) to POST PLA (122 ± 14 rpm) but increased from PRE (120 ± 14 rpm) to POST NO3 (127 ± 13 rpm) (P = .043; ηp2 = 0.30). There was no relative change in RPM opt after PLA (–0.3% ± 4.1%), but there was an increase after NO3 (6.5% ± 11.4%) (P = .049; d = 0.79). No differences were observed between the 30-s isokinetic trials. Conclusions: Acute NO 3- supplementation can enhance maximal muscle power in trained athletes. These findings may particularly benefit power-sport athletes who perform brief explosive actions.

  • A low dose of nitrate (~5 mmol) administered acutely improved maximal power during 3-4-s inertial-load cycling sprints in trained athletes.

    “A low dose of NO 3 -(∼5 mmol) administered acutely improved maximal power during 3-4-s inertial-load cycling sprints in trained athletes (128)”

    From Dietary Nitrate and Physical Performance (2018) · cites this paper as [128]

    The Abstract Methods and Results report that acute nitrate supplementation improved maximal power during 3–4-s inertial-load cycling trials in trained athletes. However, Methods > Methodology states that participants received two doses containing about 11.2 mmol nitrate in total, not a total dose of approximately 5 mmol. The indexed passages provide no page numbers. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Enhanced skeletal muscle contractile function has been observed during electrically stimulated contractions, and enhanced peak power output has been observed during isokinetic dynamometry and cycling exercise.

    “Consistent with the potential for improved weightlifting exercise performance after NO3− supplementation, enhanced skeletal muscle contractile function has been observed during electrically stimulated contractions [95,96,103], and enhanced peak power output has been observed during isokinetic dynamometry [97,123,128] and cycling [45,57,60,129,130,131,132,133] exercise.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
